\ the doubled sheets or plates` in cdgeivise position .on aiWheeledcarriage. p y

The present invention relates particularly to that class of automatic packing means ior the sheetsor plates disclosed in my Patent No, 1,688,932, granted Se tomber 11, 1923, und differs therefrom in t 1c provision of an improved .and novel operating means 'for the packin bead.

In t e drawingsf Fig. 1 'is an end viewuof theapparatus, the upper port-ion of the housings `and 4 doin oler mechanismV beingomitted since itl is standard mechanism forms no part .this

\ invention; and

Fig. `2 isa seotional elevation taken on the line Ilm-II ofFig. 1. y y Referring more v particularly tothel draws ings, the numerals 2 and 3 designate the doubler side-housings which are spaced apart and which are connected together by transverse members 4 and 5 and by other structun al members adjacent thcirupper ends (not shown).

The sheets p or plates to be doubled are passed between the housingrgs` 2 and 3 and are adapt-ed to be forced down betweena ,pair oiE doubling rolls 6 and 7 by thc doubling knife 8. p K

A pair of guide plates 9 and 1() arear-4 ranged transverselyV bet-Ween. the housings 2 and?) and are adapted to receive the doubled v sheets or plates and gnidethem downwardly onto a Wheelfcarrier ortruck A located in e passageway'B between the lower portions of the side housings 2 and ,3.

The truck A com rises aV flat chassis or body 12, axles 13, an flangedwheels 14. A

hand-brake mechanism is provided tov frio tionally engage the one` pair of wheels so as to normallyl resist free movement of the truck, and com `rises abrake-shaft jeun naled on the clliassis 12 and `providedl with a `hand operating lever 16 having a ratchet lock 17. A pair ofbrake shoes 18 are carried by the shaft 15 and adapted to engage the truck wheels.

A sheet or plate stop head 20 is secured to the truck chassis `12 adjacent one end and ef;-

tends upwardly therefrom, and is adapted to support the doubled sheets or plates in edire- Wise position as theyare delivered ontotlie f truck.

A packing mechanism is provided for packinoV the sheets or plates forwardly tof `Ward `tlie stop head 20, and comprises ahead member 21 keyed on a shaft journaled in 'bearings on the doubler side housings 2 lhe head 21 is inclined rearwardly above an d below a. point interm-ediate its ends. The ripper inclined portion `is otl .greater length than the lower portion and is adapted to torni a guide for guidino' ythe doubledsliects into position on the trucl A, While the-lower vinclined portion forms the packing portion and is inclined at substantiall.v the saine angle as the stop head so as tolie against the sheets which yare packed against said sto head. d

The doubling knife 8 is adapted .to .be op-y erated 4by a ,crank-shaft 25 journaled on the doubler housings vand having. its crank por-yy tions 26 connected to theknifeby connecting rods`27. A disk 28 lis secured to one end of the shaftr and has apin 29 eccen-V trically monnted therein 1 and projecting' therefrom. The pin 2) is positionedlop iol site to the cranks 26 or' the shaft 25 so that when said cranks are intheir upper position, the pin 29 will be in itsjlowermost position.

Av-lever SO'has one end keyedto the shaft Y 22 and .has its other end connected'to the eccentric pin `29 by a link 31. Therefore, the lever will be raised and lowered upon cach revolution ot the shaft 25 Vand vdisk 28 so as to rock the shaft 22 and packing head 21 or away from and toward ar equally sheets. When the cranksare rotated toftlieir` i Vlower position to canse the knife "8 to force the sheets between the rollsol and@ the pinl 29 will be moved'to its u )per positionsoas to raise the lever 30 an rock` the packing head 21 rearwardly to permitthe doubled sheets to fall between they head 21 and the pile of sheets on the truck A.

The crank-shaft 25 and doubling rolls 6 and 7 will be operated by an electric motor andgearing such is common in the well known forni of standarddoubler.

In operation, the carriage or truck A, is backed into the passageway B between the housing sides 2 and Suntil the head 20 is close to or in ,Contact with the packing head 2l, and the brakes 18 are set. to hold the truck against free Inovementy from this position, but will yield frictionally to allow the truck to move when force is applied thereto.

T he doubler mechanism is then set. in motion and as a sheet or plate is doubled and forced between or through the rolls (i and 7, which rolls heilig spring-pressed against the f sheet tend to complete the doublingand press the sides of the sheet closely together, while the packing head 21 will be rocked backwardlv to permit the doubled sheet to tall into positionon the truck A.

As the doubler knife 8 is elevated in readiness to permit another sheet to be doubled, the packing head will be rocked forwardly to pack the sheets and force thetruck A forward an amount equal to the thickness ot' th e doubled sheet. i n

While I have shown and described one specific embodiment of my invention it. will be understood that I do not wish to he limited thereto, since various modiiications inlay be made without departing from the scope of my invention as defined in the, appended claims. Y

I claim- L'A doubling apparatus for sheets and plates'comprising, in combination, a housing having a passageway through its` lower end through which a wheeled carrier is ad apted to pass, a wheeled carrieradapted to he lo-y cated in said passageway, said carrier being provided with an upright head at one end to support the doubled sheets or plates delivered onto said carrier, a doubling mechanism mounted on said housing, said mechanism including a doubling knife and doubling rolls, and means including a crankshaft for operating said doubling mechanism, means for receiving and guiding the doubled Sheets or plates onto said carrier, a packing head supported on said housing and adapted to he rocked back and forth to pack the doubled sheets on said carrier, said head having a constant stroke and being adapted to move said carrier forwardly a distance substantially equal to the thickness of the' doubled sheets or plates so as to position said carrier to receive the next doubled sheet or plate, andcmeans4 operable by said crankshaft for rockingsaid packing head.

2. A doubling apparatus for sheets and plates comprising, in combination, a housing, a doubling mechanism mounted on said housing, said mechanism including a doublingr knife and doubling rolls, and means including a crank-shaft for operating said doubling mechanism, a shaft journaled on said housing, a packing head secured ,on said shaft, said head being adapted to be rocked hack and forth to pack the doubled sheets, alever secured to said last-named shatt, a pin mounted ecccntrically on said crank-shaft, and a link connecting said pin and said lever so that said lever will be rocked h v cach revolution of said crank-shaft.

3. A doubling apparatus for sheets and plates comprising, in combination` a housing, a doubling mechanism mounted on said housing, said mechanism including a doubling: knife and doubling rolls, a crank-shaft, con necting rods connecting the cranks of said shaft to said knife for operating said knife, a shaft journaled `on said housing, a packingr head secured on said shaft, said head being adapted to he rocked hackand forth to pack the doubled sheets, a lever secured to said lastnained sha-tt, a pin mounted eccentrically on said crank-shaft, and a link con nccting said pin and said lever so thatsaid lever will be rocked by each revolution of said crank-shaft, said pin being positioned oppo site to said cranks relativeto the longitudinal axis of said crank-shaft.`

4. A doubling apparatus for sheets and plates comprising, in combination, a housing having a passageway through its lower end through whicha wheeled carrier is adapted to pass, a wheeled carrier adapted to he lo cated in said passageway, said carrier being provided with anv uprighthead at one end to support the doubled sheets or plates delivered onto said carrier, a doubling mechanism mounted on said housing, said mechanism including a doubling knife and doubling rolls, and means including a crank-shaft tor oper ating said doubling mechanism, connectiiur rods connecting the cranks` of said .shaft io said knife, a shaft extending transversely ol' said passageway and journaled in hearings on said housing, a packing head secured on said last-named shaft and adapted to he rocked back and forth to pack said sheets on said carrier, a lever secared to Said lastmamed shaft, a pin mounted cceentrically on said (rank-shaft, and a link connecting said pin and said lever so that said lever will be rocked by each revolution of said crank-shaft., said pin being positioned opposite to said cranks relative to the longitudinal axis of said crank-shaft.

In testimony whereof, I have hereunto set my hand.
